Gordon Ginnish, 25, made his first court appearance Tuesday before Superior Court Justice Kevin Cuddy on charges of assault to a police officer, criminal mischief and violation of a condition of release.

The judge ordered that Ginnish be held without bail until a hearing on a motion to revoke his bail can be held on May 11. Cuddy set bail at $1,000 cash but Ginnish would not be able to post it until after the hearing next month.

Ginnish was on bail for attempted acquiring drugs by deception when the incident with the police officer occurred, according to Brendan Trainor, assistant district attorney for Penobscot County. Ginnish allegedly tried to obtain methadone from a Bangor pharmacy in October using a stolen prescription pad.

He has pleaded not guilty to that charge, Trainor said.

In the incident with the police officer early Sunday morning, an intoxicated Ginnish allegedly head-butted the arresting officer so hard that the officer suffered a concussion, according to a previously published report. Ginnish also allegedly kicked out the rear driver’s side window of the cruiser.

If convicted, he faces up to five years in prison and a fine of up to $5,000 on the drug and assault charges.

Ginnish also faces up to a year in prison and a fine of up to $2,000 on the criminal mischief charge. In addition to jail time, he could be ordered to pay restitution for the damage to the cruiser.

On the bail violation charge, Ginnish faces up to six months in jail and a fine of up to $1,000.
